EWF's co-headline show with Lionel Richie at Chase Center was postponed minutes before showtime after a medical emergency involving a band member. No makeup date yet: hold your tickets for the rescheduled date, or take a refund at the point of purchase.

If you were headed to Chase Center for Earth, Wind & Fire and Lionel Richie this week, the short version is: the show didn't happen, and there's no makeup date yet. The practical version is below.

Earth, Wind & Fire's co-headlining stop on the "Sing A Song All Night Long" tour — Thursday, August 6 at Chase Center, 1 Warriors Way in Mission Bay — was postponed minutes before showtime after a medical emergency involving a member of the band. In a statement, the group said it was "unable to perform as scheduled tonight at Chase Center in San Francisco due to a medical emergency involving a member of our band." The San Francisco Fire Department responded to a call around 5:30 p.m. and transported one person to a hospital, according to CBS News Bay Area. TMZ, citing the fire response, described it as a cardiac incident. The band and Live Nation have said only "medical emergency," and no member has been named.

What ticket holders need to know. Promoter Live Nation says the show "will be rescheduled, with a new date to be announced soon." Per the band's and Live Nation's statement, hold onto your tickets — they'll be honored for the new date — or, if you'd rather not wait, take a full refund at your original point of purchase (Ticketmaster if that's where you bought them). As of Thursday, no rescheduled date, refund deadline, or claim window had been posted, and it's not confirmed whether Lionel Richie will headline any San Francisco makeup date. Watch the band's channels and Ticketmaster for the update rather than relying on resale listings.

The insider read. Don't rush a refund in the first 24 hours unless you truly can't make a future date. Reschedules for arena co-headliners tend to land within weeks, and holding your original ticket usually keeps your seat location. If a new date drops and it doesn't work for you, the point-of-purchase refund is still there — postponement (not cancellation) typically leaves that window open. Also worth noting: this tour has already been bumped once, when a June dizziness episode involving Richie forced two earlier postponements, so a firm SF date may take a beat.

If you'd blocked out the evening anyway, Thrive City, the plaza outside the arena at 3rd and 16th, is free and open — a low-stakes fallback while you wait for the real date.
